COMBINED GAS AND ELECTRIC-LAMP FIXTURE.

SPECIFICATION formingpart of Letters Patent No. 256,701, dated April 18,1882.

Application filed Novemher28,1881. (No model.)

To all'whom it may concern:

Be it known that I, EDWARD H. JOHNSON, of New York. in the county of NewYork and State of New York, have invented a new and useful ImprovementinCombined Gas and Electrio-Lamp Fixtures; and I do hereby declare thatthe following is a full and exact description of the same, referencebeing bad to the accompanying drawing, and to the letters of referencemarked thereon.

When a house is fitted'for electric lights which is already suppliedwith gas-fixtures it may be desired to so arrange the two systems thateither may be used, or that. they may be usedsimultaneously, the samefixture snfficin g for both lights.

The object of this invention -is to construct a fixture so that it mayat any time be used either for incandescent electric lights or gas, orboth, without in any way changing the nature of the fixture, and withoutrequiring any more complicated operations than those of shutting on oroh the gas, or making and breaking the electric circuit; and, further,to utilize the gas-fixtures already in the house for this purpose in amanner perfectly simple and easy of performance. v

The annexed drawing is a perspective view :of a gas-fixture having myinvention attached to it.

A represents any ordinary gas-bracket, chandelier-arm, or other similardevice, and B is any suitable burner attached to it in the usual way.

U is the cock for turning the flow off and on.

1 2 and 3 4 are the wires of two electric circuits.

D D is a hollow tube, which may be of any convenient form. On each endof the tube is a socket, E, for holding an incandescent electric lamp,F. The tubeD D is provided with an openin g at its center, through whichthe insulated wires of the circuits 1 2 and 3 4 enter,

one circuit passing to one lamp and one to the other.Circuit-controllers may be attached to the sockets or elsewherein thecircuits. A shoulder, G, is formed. at the middle of the tube D, havinga tubular projection or sleeve, H, extending upward from it, with anaperture below, this projection conforming in shape to the burner B andfitting over the same.

- I is a set-screw.

It will thus be seen that the tube B, containing the wires and carryingthe sockets and lamps, may be set directly upon the end of ing a sleeveto place over the burner at one I end and a lamp-socket at the other mayeasily be used.

What I claim as my invention is The combination, with an arm of agas-fixture, of an incandescent electric lamp having proper wireconnections, and attached to such arm by aring or hollow support passingover the gas-burner, the gas-burner and the electric lamp being capableof use either simultaneously or independently of each other withoutchanging their relative position, substantially as set forth.

This specification signed and witnessed this 19th day of September,1881.
